Completion Fluids

Customized solutions to maximize productionProducing zones require special care in order to encourage maximum production. Knowing how to interpret the complexities of your reservoir, Baroid completion fluid experts can recommend completion fluids specific to your wellbore conditions that can maximize production.

Engineered fluids that minimize damage to the reservoirBaroid’s completion fluids are engineered to minimize damage to the reservoir. Through optimization of services, systems, and applications, Baroid’s completion fluids provide high performance wellbore management using innovative technologies.

Comprehensive portfolioWith a complete suite of completion fluids to choose from, our engineers will customize a solution that works for you. We have solutions to control formation pressure, minimize damage to the production zone, and prepare the well for production. Our completion fluids optimally prepare, repair, clean out, and complete the wellbore.

A combination of high fluid densities, deep wells and elevated bottom hole temperatures proved to create a corrosive environment for the operator’s rented drillpipe. Although general corrosion was controlled down to very acceptable rates, signs of pitting corrosion were observed on corrosion rings. Pitting corrosion is an extremely localized form of attack which can rapidly perforate metal. Pitting can be far more damaging than general surface corrosion.

The operator was seeking methods to save time associated with displacement operations. The established practice was an indirect
displacement of a synthetic-based mud (SBM) firstly to seawater and then to completion brine. The two-stage indirect placement method requires the circulation of sea water for up to 10 hours in order to achieve suitable clarity. At this point, the sea water is displaced to clean brine. Historically, no displacement modeling or chemical cleaners had been used during these operations.

The drilling hazards of the area required the use of an aerated fluid due to lost circulation risks. As well as the corrosive action of the aerated fluid, H2S influx was a potential hazard. Previous wells in the area serviced by other fluids service companies failed to control corrosion and resulted in the destruction of an entire rented drillstring, costing upwards of $500,000. Baroid was asked to propose a drilling fluids and corrosion control program.

Baroid consulted with their Houston Global Technical Support group to design a customized solution and implemented an enhanced corrosion control treatment, providing the operator with a savings of between $500,000 and $1,000,000.
